Filed: 1995-02-22
Abstract: PURPOSE: To provide a controller for a hot water storage type electric water heater which keeps errors from affect computation of energization time as contained in a measured value of a temperature sensor for measuring the temperature of cold water supplied significantly. CONSTITUTION: The temperature T1 of cold water supplied into a hot water storage tank is detected by a first temperature sensor 3a. Second to fourth temperature sensors 3b-3d are arranged at a boundary position between individual hot water blocks of the hot water blocks B1-B4 in an area at higher positions than the first temperature sensor 3a. An energization time computing means 7 computes energization time H using a formula of H=(T-T1)×K 1+(T-T2)×K2+(T-T3)×K3+...+(T-Tn)×Kn, wherein K1-Kn are coefficients indicating energization time necessary for raising the temperature of cold water within the first to fourth hot water blocks B1-B4 by 1 deg.C.  In this formula, as a measured value T1 of the temperature sensor 3a is used only once, there is no significant effect on the energization time even when errors are contained in the measured value T1 of the temperature sensor 3a.

Title: Rotational direction identifying method for two-phase unipolar sensorless motor
Inventor: FUJII HIROMASA
IPC: H02P6/06
Filed: 1992-02-20
Abstract: PURPOSE:To provide a rotational direction identifying method for two-phase unipolar sensorless motor through which reverse rotation can be prevented by recognizing the rotational direction of the motor. CONSTITUTION:The rotational direction identifying method is applied on a fan motor having a cogging stop position, i.e., a magnetic stop position, different from an electric lock position, i.e., an electric stop position, and the method takes advantage of the asymmetry in the waveform of counter electromotive force induced in the stator through rotation of the rotor. In other words, only the waveform of counter electromotive force is selected (101) and thus selected waveform is subjected to differentiation (102), zero-cross comparison (103) and integration (104) and thus integrated waveform is compared (105) with a not integrated waveform thus identifying the rotational direction of the motor.

Title: Piezo-electric valve device
Inventor: ITOU TOSHIHIKO
IPC: F16K17/04
Filed: 1982-03-05
Abstract: PURPOSE:To eliminate the bad influences of a question brought out when supporting a valve with metal instead of oil as in a usual technique on the dimensional accuracy of a device at its assembling and the thermal strain of a casing  by allowing a piezo-electric body to drive one end of a valve body as well as to support the other end of the valve body with hydraulic pressure while utilizing the extension force of the piezo-electric body when turning on electricity. CONSTITUTION:When a piezo-electric body 7 is turned on, the body 7 stretches in the axial direction in response to the magnitude of its applied voltage. This stretching force acts in the vertical direction, and when it comes to stretch in the upper direction, fuel oil within a hydraulic chamber formed on the top of a piston upper 5 is required to be discharged outward. But, a steel ball 92 blocks up a stop 93 at this instant, preventing the movement of the piston upper 5 in the upper direction. Accordingly, a piston lower 6 moves downward, allowing its projection 63 to force down the valve body 8. In such a situation, high pressure fuel is leaked via a groove 82 because a ring-shaped groove 24 is opened in its lower part.

Title: Signal processing circuit
Inventor: YANO TAKASHI
IPC: H04N5/225
Filed: 1990-02-16
Abstract: PURPOSE:To facilitate sampling of a high frequency signal by detecting a signal level at a position desired to be sampled in an input signal, latching the detected level for a prescribed period and sampling the signal within the latch period. CONSTITUTION:A clamp pulse V2 changes to a high level synchronously with a pedestal period t0 of an input signal V1. When the clamp pulse V2 is at a high level, a switch S1 is controlled to be turned on synchronously therewith. Every time the pedestal period to appears, since a reference voltage Vref is fed to a line 11, the AC component V1' of the input signal V1 is clamped to the reference voltage Vref. Thus, the AC component V1' whose level changes with respect to the voltage level of the reference voltage Vref is fed to a peak hold circuit 4. Thus, even when a time a level of a high frequency analog signal desired to be latched is very short, the time latching the level is expanded to a desired time and accurate sample-and-hold is implemented without special setting of high accuracy of a pulse width and a phase or the like of a sample- and-hold pulse.
